The function 'dproxyme' estimates a\nfactor model of discrete proxy variables using an EM algorithm\n(Dempster, Laird, Rubin (1977)\n<doi:10.1111/j.2517-6161.1977.tb01600.x>; Hu (2008)\n<doi:10.1016/j.jeconom.2007.12.001>; Hu(2017)\n<doi:10.1016/j.jeconom.2017.06.002> ). The function 'cproxyme'\nestimates a linear factor model (Cunha, Heckman, and Schennach\n(2010) <doi:10.3982/ECTA6551>).",
